MOST OF US COLLECT MEMORIES and a few relics, but photographers and filmmakers literally assemble traces of the world, build a piece of an archive every time they go to work. Chris Marker’s extraordinary CD-ROM Immemory is an attempt to make such an archive available in the form of a visual essay. Only visual? There are snatches of sound here and there, but Marker mainly invites us to see things, in every sense—and then remember and meditate. He gives us poems, pages of prose, book covers, postcards, book illustrations, paintings, posters, telegrams, letters, clips of film, and above all, hundreds of photographs taken in dozens of places: China, Cape Verde, Korea, Japan, France, Iceland, Cuba, Russia. The disc is an immense album of faces, gestures, buildings, statues, and landscapes, a fragmentary recollection of the last century.
